Free WCAG accessibility toolbar for WordPress. 5 built-in tools + Pro upgrade with 21 tools, AI scan, and IS-5568/EAA compliance.

== Description ==

**Ziko Accessibility** adds a professional accessibility toolbar to your WordPress site, helping you comply with **WCAG 2.1 AA**, **Israeli Standard IS-5568**, and the **European Accessibility Act (EAA)**.

The plugin provides real accessibility tools that help visitors with disabilities navigate your content — not a cosmetic overlay.

= Free Version (5 Tools) =

* **Font Size** — increase/decrease text size in 3 levels
* **High Contrast** — enhanced contrast mode for better readability
* **Link Highlight** — outlines and underlines all links on the page
* **Reading Guide** — horizontal ruler follows the mouse for easier line tracking
* **Reset** — restore all settings to default

All settings persist in localStorage so visitors keep their preferences across pages. **No external requests. No account needed. 100% local.**

= Pro Version (21 Tools + AI Scan) =

Upgrade to Pro for the complete accessibility toolkit:

* Everything in Free, plus:
* **Text Spacing, Line Height, Letter Spacing** — improved readability controls

The toolbar is fully localized in Hebrew with right-to-left layout, designed specifically for Israeli websites. English interface also supported.

This plugin connects to the Ziko API (ziko.co.il) in the following cases:

**Pro License Activation and Validation (Pro only):**

When you activate a Pro license key, the plugin sends your license key and site domain to the Ziko API for verification. A daily cron job validates the license to ensure it remains active.

* When: on activation, daily validation, and deactivation
* [Privacy Policy](https://ziko.co.il/privacy)

**Pro Widget CDN (Pro only):**

When Pro is active, the accessibility widget JavaScript is loaded from the Ziko CDN. This provides the full 21-tool widget with automatic updates.

* CDN URL: https://ziko.co.il/a11y/widget.js
* Only active when a valid Pro license is configured
* The user explicitly opts in by entering a license key

**The free version makes NO external requests and works entirely offline.**
